摘　　要：通过对某带式输送机减速器输入轴系转子系统进行受力分析,得到其数学模型,并讨论了齿轮和带轮由于具有偏心不平衡质量而产生的不平衡响应。利用有限元分析软件ANSYS建立其有限元模型,得到了不平衡响应中的轴系轴线的幅频特性曲线和轴线轨迹。通过分析可知输入轴系的额定转速低于一阶临界转速,转子主轴属于刚性转子。ANSYS仿真分析结果和理论计算结果吻合较好。This paper analyzes the stress of the input shaft rotor system in a reducer of belt conveyor, and obtains its mathematical model. The imbalance response of gear and pulley generated by the eccentric unbalance quality is discussed. A finite element model is established by the finite element analysis software-ANSYS, the axis trajectory and the amplitude- frequency characteristic curve of shaft and axis in the imbalance response are obtained. The results show that the working speed is lower than the first critical speed, and the rotor shaft is rigid rotor. The simulation result is in good agreement with theoretical analysis.
